Question

The displacement of a particle moving in a straight line
is described by the relation, s = 6 + 126-27. Here s
is measured in metre and t is in second. The distance
covered by particle in first 5 s.is
(a) 20 m
(6) 32 m
(c) 24 m
(d) 26 m​

Answer 1

Explanation:

here

s=displacement

instantaneous speed = s/t

105/5

=21m
